Mechanical and thermal properties of UV cured mixtures of linear and hyperbranched urethane acrylates

► UV curable mixtures of linear and hyperbranched urethane acrylates. ► Hyperbranched urethane acrylates with the same degree of acrylation and different non-acrylic end-groups. ► Non-acrylic end groups originating from isononanoic acid and soybean fatty acids. ► The nature of non-acrylic end-groups has great influence on the properties of uncured and UV cured mixtures.
